PURPOSE:To carry out the scraping of barley cake, rapidly and surely, and to improve the efficiency and save the labor cost of the cake removing operation, by attaching cake-scraping plates to both sides of a stirring cross beam fixed to the rotary shaft in the main body of the tank, wherein the cake scraping plate is made movable vertically by a link arm. CONSTITUTION:The cross beams 18-20 are lifted to the upper position U with the rotary shaft 17 by the upward motion of the lifting means 26 through the vertical shaft 27, and the hole of the perforated plates 35 at the both ends of the cross beam 18 is engaged with the pin of the lower hood 40 of the scraping plate lifting means 37. The supporting shaft is rotated by the motor, and the worm wheel is rotated to lower the cross beams 18-20 to the lower positions by the action of the link arm 25. Then the lifting means is moved downward to lower the cross beams 18-20 to the lower positions, and the cake scraping plate 24 at the lower position is brought into contact with the filter mesh at the lower face and with the inner surface of the tank at the extreme ends. When the rotating means is driven to rotate the cross beams 18-20 through the vertical shaft 27 and the rotary shaft 17, the barley cake on the filter mesh is scraped by the cake scraping plate 24 to the wall of the tank, and discharged completely from the cake discharge port 14.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lees removing device that filters wort, which is a raw material for beer, and feeds it into a filtration tank that separates it into modified wort and refreshing wort.

The conventional wort filtration tank has an inner diameter of 6 to 9 m and a depth of 2 m.
8 Filter the wort supplied into the tank to a depth of about 1 m using a filter net placed on the bottom of the tank body of fjf-,
The cooling wort is taken out of the tank, but after the filtration is finished, it is necessary to discharge the wort remaining in the wort and the wort out of the tank.

For this reason, conventionally, a stirring device consisting of a cross beam with stirring blades attached to a rotating shaft inside the tank body was used, and the stirring blade was rotated 45 mm in the direction of rotation φ. The steel is turned into a white juyo A, and the cross beam is turned (Koyori Hayashi y
Kasutori 1 who caught the transmigration with the stirring blade and sank into the proper place of the extinction net]
Either the lees is drained out of the tank, or the lees are washed with a stirring blade, so a fairly strong structure is required. In addition, it was not necessary to sweep up the sludge that was harsh off the coast or between the rotation gap with the inner wall of the tank. Furthermore, 45 questions were asked about the 4 stirring blades (one reviewer said that the operation was similar to that of a fire because the stirring blades were made by hand).

The purpose of the defense is to carry out the sweeping work with a dedicated return plate at J3 speed, and to make it possible to set the scraping plate automatically. This is intended to improve the efficiency and labor-saving of self-discipline work.

The invention of Iha V''1 of Guan Bha is a wort filtration tank in which lees sweepers supported by link arms so as to be movable up and down are arranged on both sides of a stirring cross beam fixed to a rotating shaft inside the tank body. To provide a lees removal device for a wort filtration tank, which is constructed so that barley grains can be quickly and reliably discharged while collecting them on the outer circumferential side of a tank main body.
